Interaction of CO2 and Light on Plant Growth: Sometimes people claim that the aerial fertilization effect of atmospheric CO2 enrichment will be reduced or non-existent when environmental conditions conducive to robust growth are less than optimal. We here evaluate that claim with respect to light intensity.
